Woop, a citizen; of the United 'States of America, residing at Uniontown, the. county of Fayette and State 0f;Pennsyl-.

vania, have invented certain new and useful Improvements in cable Roller Brackets, of which thefollowing is a specification.

'This'invention relates to an improvement in brackets designed for the support of the ,cablevcarrying rollers, used in m ne and similar-haulage systems.

The invention 1s particularly directed :to abracket, with which the roller proper liability of undue wear on the bracket or cable; the mounting of the roller in the bracket being such as to permit the con- T-he invention is illustrated inthe accom- -Fig, 1; is a perspective viewillustrating ,a roller; and the -bi'acket.mount1 ngs therefor .Fig. 2 is a;broken perspective of one end of the roller, showing thebearing-bracket and oiling .ring arranged thereon- Fig. 3 IS a longitudinal sectlon through Fig. i is a transverse As is usual in'haulagesystemsof this type, each roller 1 is supported in bearing brackets 2, secured to transverse supports, as ties 3, the rollers being designed to support a moving cable 4: for use in hauling.

In cable hauling systems of this character, the necessity for slackness in the cable causes portions of the cable to frequently ride off of one or more of the supporting rollers, following which the cable in its tend ency to return to the roller under strain on the cable, engages the bracket and tends to a breakage of such bracket or an undue wear on the cable.

T he present bracket is constructed with a view to avoiding this wearing contact between the cable and bracket, in the attempt of the displaced portion of the cable to re turn to the roller, the means provided to this end serving to guide the cable onto the roller without undue wear of the cable or bracket.

Thetimproved bracket is formed with a hollow central box-like portion 5, open at .thegtop and formed in the'inner wall with a recess 6, through which theshaft 7 of the roller 1 is adapted to extend. A'cover 8 is adapted to overlie and close the box-like portion 5, said cover being pivotally connected atone end to an externalear 9 at one end of the box-like extension, and adapted to engage and be removably secured to a similar .ear at the opposite end of the extension, thus removably holding the cover in place.

a The box-like extension 5 of the bracket is formed on its outer side, approximately in line with the recess 6, with a guide extension 10, the bottom of which aligns with the bottom of the bracket, and the outer rounded guiding edge 11 of which extends upwardly and inwardly toward thebracket at approxi- Inately.45 to the vertical, the upper end of Y the guide extension terminating in line with 1 the top of thebox-like extension 5 ofthe bracket and. forming therewith a slight shoulder 12. A cooperating guiding element 13.is carried by the cover, this cover guiding elementhaving its lower end resting upon theshoulder12 and .its outer surface thereby aligned withthe outer surface or guiding edge 11 of the,guiding element 10. The guiding element 13 has its guiding edge 14 upwardlynand inwardly curved, this guidingedge terminating abruptly in line with the inner. edge of the bracket proper and at a point above the rollerl.

Thus, inthe event the. cable is displaced at either side of the roller 1, as when the cable is slack, subsequent strain on the cable, tending to return the cable to its normal line of operation, that is, on the rollers 1, will cause the cable to engage the particular guiding edges 11 and 14 of the elements 10 and 13, and thus be caused to readily return onto the rollers without undue wear on any portion of the bracket or cable. Obviously, the guiding element 13 will be subjected to greater wear than the guiding element 10, as the cable in approaching the roller engaging position, is drawn more tightly than when engaging the lower guiding element 10. Thus, the guiding element 13 will wear more rapidly in use than the guiding element 10, and hence provision is made, through the removable connection of the guiding element 13 with the cover, for renewing this guiding element 13, as it may become necessary.

Theinvention also contemplates a specific structure for supporting the shaft Twithin the box-like extensions 5, to take advantage 7 of a well known continuous self-oiling systern. In this use, the box-like extensions become oil receptacles, and are adapted to 'be'readlly filled with oil to the predetermined level by merely opening the cover 8.

The shaft 7 is supported at its ends in hanger plates 15, the upper plate-like portions of which are adapted to fit in the upper portions of the box-like extensions 5, the

ends-of the plate-like portions ofthe hang- 'ers being-supported on shoulders 16 at the The hangers also include rounded extensions '17 depending from the plate-like portions and" formed with openings 18 to loosely receive the shaft 7. The plate-like portions of the hangers are formed with longitudinally respective ends of the box-likeextensions 5.

extending slots 19, and the rounded extensions 17 are spaced apart in accordance with the transverse dimension of the slots. An

- oiling ring 20 is adapted to'loosely surround the shaft 7, fitting between the extensions 17 and in the slot-19 of each hanger, thisring having a diameter suiiicient to cause the lower portion thereof to extend into the body of oil below the shaft. This system of continuous oiling through the use of the ring'desc'ribed is well known in the art, but

7 the combination of the ring of ahanger lplate lo0sel'y supported in bearing boxextensions, the 7 said hanger. plates serving as means for 'limiting the endwise play of the ring,- is a particular improvement in such oiling systems' 'andforms a material part of the present invention. v

The guiding element 13 is preferably 'r'emovably securedand placed to the cover 8,

' by a screw 21', which extends'from the inner side of the cover and threads into the guiding, element, Of course, the lowergedge of the guiding element 13 is shaped toiaccu "pression'21, forming an oil channel leading fromsuch opening 18. The oil dripping from the shaft or pin-7 is thus directedback into the reservoir rather than to permit it to escape on the outside :of the housing. Claims:

' 1 1. A bracket for supporting cable carryfing rollers, including a hollow box-like extension to receive theshaft of the roller, a cover for closing sald' extension, a cable guiding element on the outer wall of the box-like extension, and a cable guiding element on the cover, the latter guiding element aligning with the first mentioned guiding element and'terminating at the inner side-of the bracket on a plane above the roller.

J 2. A- roller bracket having a box-likeex,

tension to receive the shaft of the roller, a cover for such extension, a cable guidesecured to the outer wall of the box-like extension, and a cable guide secured to said cover, the cable guide on the cover having a curved guldlngsurface and termlnatlng' on a'plane above: the surface of the roller,

3; A roller bracket'having a box-likeex 'tens'ion toreceivetheshaft of the roller, a

cover for such extension, a cable guide securedto'the outer wall'of the box-like extension, and a cable guide. removably secured to said cover, the cable guide on the cover on a, plane above the; surface of the roller. 7 v a In testimony whereof I aflix my signature.
